A colleague and I are attempting to graph a scatterplot which shows the results of a latent growth curve analysis. The x axis is the mean latent growth slope for concern about economy, and the y axis is the mean latent growth slope for support for Barack Obama. We want to show two groups on the same scatterplot - Whites and African Americans. We have a dummy variable in the analysis for race. We would like to show the scatters for the two groups with different colors. Is this possible, and, if so, how would we do it. Help would be much appreciated, thanks, Tom
